Abstract

This study aimed to determine the effect of coffee husk waste application and shallot extract soaking on the growth of cat’s whiskers (Orthosiphon aristatus) cuttings. The research employed a factorial Randomized Block Design (RBD) consisting of two factors with 48 experimental plots. The first factor was the application of coffee husk waste, symbolized as “L,” with four treatment levels: L0 = 0 g/polybag (without coffee husk waste), L1 = 75 g/polybag, L2 = 150 g/polybag, and L3 = 225 g/polybag. The second factor was shallot extract soaking, symbolized as “B,” with four treatment levels: B0 = 0 ml/L of water, B1 = 5 ml/L of water, B2 = 10 ml/L of water, and B3 = 15 ml/L of water. Thus, there were 16 treatment combinations with three replications. The observed parameters included time to shoot emergence, number of shoots, plant height, number of leaves, leaf area, and survival percentage. The results showed that the application of coffee husk waste and shallot extract soaking had no significant effect on the growth of cat’s whiskers (Orthosiphon aristatus) cuttings across all observed parameters.

Abstract

Basil (Ocimum basilicum L.) is a horticultural plant widely used as a fresh vegetable and herbal ingredient. Efforts to increase basil growth and production can be achieved through environmentally friendly organic fertilization, one of which is the use of cow manure and eco- enzymes. The purpose of this study was to determine the response due to the provision of eco enzyme and cow manure on the growth and production of basil plants. This research method used a factorial randomized block design (RAK) with two factors. The first factor was the provision of cow manure with 4 levels, namely S0 = no treatment, S1 = 200g, S2 = 300g, S3 = 400g. The second factor was the provision of EE with 4 levels, namely E0 = no treatment, E1 = 10ml, E2 = 20ml, E3 = 30ml. The observation parameters of this study were plant height, stem diameter, number of primary branches, fresh weight, root length, flowering age. The results of this study are expected to provide recommendations for effective organic fertilization to increase basil plant productivity sustainably.

Abstract

The study was conducted to determine the effectiveness of planting media and liquid organic fertilizer on the production of pakcoy mustard in a hydroponic system. Using a factorial Completely Randomized Design (RAL) method. The first factor of planting media consisted of four levels: M1: TKKS, M2: TKKS+cocopeat (75:25), M3: TKKS+cocopeat (50:50), M4: TKKS+cocopeat (25:75). The second factor of liquid organic fertilizer consisted of four levels: K1: AB Mix, K2: POC 10%, K3: POC 15%, K4: POC 20%. The total treatment was 16 combinations and 32 experimental units. The results of statistical tests showed that the combination of planting media and liquid organic fertilizer from fruit waste had no significant effect on plant height and number of leaves, but had a very significant effect on leaf width, leaf length, leaf area, sample weight, and weight per plot. In addition to the control treatment, the use of TKKS+cocopeat (75:25) planting media and 10% POC provided the best results, thus potentially increasing pak choy mustard production.

Abstract

The aim of this study is to find out how well eco-enzyme (EE), which is made from household waste, stops the pathogenic fungus Fusarium oxysporum from growing. An eco-enzyme is a fermentation solution produced from a mixture of organic waste, sugar, and water. In this study, various types of agricultural waste, such as fruit peels, vegetable waste, or other plants parts, were used US raw materials for making Eco-enzyme. The method used includes making EE with 2 types of raw material composition and various dilution concentrations of eco-enzyme dilution, namely 1: 0; 1: 10; 1:50; and 1: 100. Eco-enzyme testing was carried out in vitro on the growth of F. oxysporum mycelium. The results showed that Ecoenzyme from a mixture of fruit peel and vegetable waste had the highest inhibitory power against F. oxysporum at a dilution variation of 1: 100. This study concludes that ecoenzyme made from agricultural waste has the potential as a biological control agent against F. oxysporum. Using eco-enzymes can be an environmentally friendly solution for controlling plant diseases while reducing agriculture waste and overcoming environmental pollution.

Abstract

Lettuce (Lactuca sativa L.) is a type of horticultural plant that has high nutritional content and economic value, with good prospects for development. Lettuce is an annual plant that is easy to cultivate in various types of land and has a wide market. The research was conducted to determine the response of lettuce plant production (Lactuca sativa L.) to the application of lemna leaf compost enriched with goat manure and the use of variations of liquid organic fertilizer as ecoenzymes derivative in a hydroponic system. This research used a factorial Randomized Complete Block Design (RCBD) consisting of 2 factors with 5 treatments and 3 replications. The first factor was the variation of liquid organic fertilizer from ecoenzymes at 5 levels: P0 = AB Mix (control), P1 = POC 1 (Pure EE), P2 = POC 2 (EE + egg shells + pineapple), P3 = POC 3 (EE + moringa leaves + insulin leaves), P4 = POC 4 (EE + guava leaves + sweet potato leaves + long bean leaves), P5 = POC 5 (EE + water spinach + baby corn). The second factor was the concentration of ecoenzyme at 3 levels: E0 = 0%, E1 = 25%, E2 = 50%. The observed parameters in this research included plant height (cm), number of leaves (leaves), fresh weight per plant (g), stem diameter (cm), plant weight per plot (g), and root length (cm). The results showed that POC 5 (EE + Water Spinach + Baby corn) provided fairly good results, ranking second after AB Mix, in terms of plant height (cm), fresh weight per plant (g), stem diameter (cm), plant weight per plot (g), and root length (cm). This indicates that a combination of more diverse and natural organic materials can optimally support plant growth.

Abstract

Bioz Nutrition is the product of second-stage fermentation of eco-enzyme (EE) or Garbage Enzyme (GE) for 21 days with the addition of specific organic materials. This study aimed to evaluate the potential of Bioz in enhancing plant nutrient content and exhibiting antibacterial activity as a natural disinfectant. Two types of Bioz, coded Bioz1-n and Bioz2-n, were produced through a process involving four main stages: the production of EE from pineapple and orange waste via anaerobic fermentation for 100 days; the production of Bioz through further fermentation of EE for 21 days with added organic materials; analysis of the chemical composition (nitrogen, phosphorus, potassium, and pH) and evaluation of antibacterial and antifungal activities; and testing against S. aureus (Gram-positive) and E. coli (Gram-negative) using the disc diffusion method. Chemical analyses were conducted using the Kjeldahl method (N), UV-Vis spectrophotometry (P and organic carbon), atomic absorption spectrophotometry (K), and a pH meter. Antibacterial and antifungal activities were tested at various dilution ratios of EE to water (1:0, 1:10, 1:50, and 1:100). The results showed that second-stage fermentation improved the nutritional content of Bioz and that a 1:10 dilution (Bioz1-1 and Bioz2-1) was the most effective in inhibiting bacterial growth, indicating its potential as a natural disinfectant. This process provides a sustainable approach to utilizing agricultural waste, adding economic value while supporting environmentally friendly agricultural and household applications.
